Lucent Technologies today announced that it has signed a contract with Wenzhou Telecom, a subsidiary of Zhejiang Telecom, to help improve its network capacity in China's Wenzhou province.
Lucent's advanced optical networking products will be used in the reconstruction of Wenzhou Telecom's synchronous digital hierarchy (SDH) network, increasing the network's transport capacity and enabling new revenue-generating services.
According to the terms of the contract, Lucent will supply the LambdaUnite(R) MultiService Switch (MSS), Metropolis ADM MultiService Mux, the WaveStar TDM 10G and the WaveStar ADM 16/1. Lucent's products, developed with the help of scientists and engineers from Bell Labs, Lucent's research and development arm, will help Wenzhou Telecom build a cost-effective optical network that supports both voice and data traffic and will allow Wenzhou to offer Ethernet, personal handy-phone system (PHS) and transport -based data services to its customers.
Developed by Bell Labs, the LambdaUnite MSS bridges traffic between data-intense metro networks and high-speed optical core networks, connecting cities, campuses and corporate networks to larger, long-haul public networks. The product enables service providers like Wenzhou Telecom to seamlessly upgrade their networks and enables them to deliver new value-added services such as gigabit Ethernet. The compact size and low energy requirements of LambdaUnite MSS also means operators can make significant cost savings compared to traditional systems. This flexible single-shelf system was recently optimized for smaller metro applications, supporting in-service upgrades from 160G to 320G, as well as to 640G, allowing the system to grow when network capacity increases. Mesh restoration capabilities were also added to help carriers migrate to new mesh-based networks, while at the same time, leveraging traditional restoration architectures.
Metropolis ADM serves as an integrated Ethernet-over-SDH multiplexer, enabling carriers to migrate from existing TDM networks to data-aware packet networks. Adding data services to optical networks increases revenue potential for customers and helps them offer a wide variety of new Ethernet services. Metropolis ADM integrates seamlessly into carriers' existing infrastructure, avoiding the need for an overlay network built for new services. Its low power consumption and small footprint will further help carriers save on operating expenses.
The WaveStar TDM 10G (STM-64) will enable Wenzhou Telecom to deliver optical services at rates up to 10 Gb/s per wavelength and support currently commercialized and next generation planned services through a scalable and flexible system. The system also allows carriers to reduce operating expenses through advanced self-healing networks and superior carrier grade reliability. It offers flexible integration of Ethernet/SDH with Gigabit Ethernet capabilities. With a deployed base of more than 25,000 systems worldwide, the WaveStar ADM 16/1 product is Lucent's successful optical multiplexer for the SDH market, and can be used for interoffice, access or regional applications. The system does this by combining multiple low-speed electrical and optical inputs into a single 2.5 Gb/s signal.
